Review on iWUNTONG Adult Bike Helmet: Removable Sun Visor & Reflective Stripe, Lightweight and Adjustable for Mountain Biking by Sammie Rodriguez

As other reviews have said, the helmet is small by US standards. I'm average height and it fits snugly into the harness system at maximum stretch meaning half the adult male can't fit in. For the price, the elaborate adjustments surprised me. They allow you to perfectly adjust the helmet to the size of your head. Unfortunately, the handwritten font is so small that it cannot be read without a magnifying glass. Nevertheless, the low contrast of the images makes the text illegible. I had to fiddle around a bit to get a good fit. For example, a soft roll fixes an additional strap. Make sure the velcro is facing away from the skin to avoid irritation. Once I find a comfortable fit, I don't even notice the helmet on my head at all.
